It is often said that beauty is subjective.
Conclusion
Beauty is not subjective (it's objective).
Evidence
If you look at what earlier cultures considered most beautiful, you'll be stunned by how similar it is to our standards of beauty. What was considered beautiful then is still considered beautiful now.
Evaluate
Given That [evidence] Earlier cultures seemed to share similar standards of beauty with our current society
How Can We Still Argue That [anti-conclusion] Beauty is subjective?
I guess we could say that the standards then and the standards now are both subjective, but they happen to match.
For example, it might be the case that an answer to the question "which flavor of ice cream is the best?" is subjective, even if an entire school bus full of 3rd graders comes to the consensus of "chocolate".
Maybe it's even causally related. Like the answer to the question, "Which sport is better: basketball or baseball?" is subjective, but maybe me and my dad and his dad and his dad all pick baseball, because each of us was raised in a house that revered baseball.
In that way, the fact that our Dad's subjective preference was for baseball may have influenced our subjective preference for baseball. The fact that everyone in our family seems to prefer baseball doesn't make that an objective (or hereditary) evaluation. It could just be that one person's subjectivity gets carried down the line and impacts others'.
Goal
Stay flexible, and look for a way to explain how .
